In my opinion, regulation, practicality, and stability are definitely required for the mass adoption of crypto as a payment method/currency.
What are your opinions on this?
In as much as Bitcoin can't gain stability and regulation it's impossible to adopt Bitcoin as a generally accepted payment method or as a legal tender. Outside all this Bitcoin don't have an intrinsic value it rely solely on fiat currency to get it's value. Another pressing issue is it's high volatility. Unless Bitcoin can counter all this limitations it's would be difficult for Bitcoin to be a legal tender
